/sys$common/syshlp/HELPLIB.HLB  —  RTL Routines, LIB$  LIB$EMODH
    On OpenVMS VAX systems, the Extended Multiply and Integerize
    routine (H-Floating-Point Values) allows higher-level language
    users to perform accurate range reduction of H-floating
    arguments.

    This routine is not available to native OpenVMS Alpha programs
    but is available to translated VAX images.

1  –  Returns

    OpenVMS usage:cond_value
    type:         longword (unsigned)
    access:       write only
    mechanism:    by value

2  –  Arguments

 floating-point-multiplier

    OpenVMS usage:floating_point
    type:         H_floating
    access:       read only
    mechanism:    by reference

    The multiplier. The floating-point-multiplier argument is an
    H-floating number.

 multiplier-extension

    OpenVMS usage:word_unsigned
    type:         word (unsigned)
    access:       read only
    mechanism:    by reference

    The left-justified multiplier-extension bits. The multiplier-
    extension argument is an unsigned word.

 floating-point-multiplicand

    OpenVMS usage:floating_point
    type:         H_floating
    access:       read only
    mechanism:    by reference

    The multiplicand. The floating-point-multiplicand argument is an
    H-floating number.

 integer-portion

    OpenVMS usage:longword_signed
    type:         longword integer (signed)
    access:       write only
    mechanism:    by reference

    The integer portion of the result. The integer-portion argument
    is the address of a signed longword integer containing the
    integer portion of the result.

 fractional-portion

    OpenVMS usage:floating_point
    type:         H_floating
    access:       write only
    mechanism:    by reference

    The fractional portion of the result. The fractional-portion
    argument is an H-floating number.
